STOP-MOTION FOR B-OVING-FRAMES.

T 0 all whom it may concern:

Be it known that I, MAURIoE NoLnr, citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have invented new and useful Improvements in Stop-Motions for Roving-Frames, of which the following is a specification.

My invention pertains to the automatic .stopping ofroving frames and it consists in improvements andthe bar by which said device is carried. Fig. 3 is a side elevation of the same. Fig. 4 is a vertical section taken in the plane indicated by the line 4-4 of Fig; 2. Fig. 5 is an enlarged view of the tappet through which the latch-releasing device is actuated. i

Similar letters designate corresponding parts in all of the views of the drawings, refer-ring to which -A is the rectilinearly? movable rack usually employed in roving frames to traverse the i belt upon the cones, which beingwell known are not shown in the drawings. During the working of the. machine the said rack A is- 4.0

gradually moved the direction indicated by'the arrow No. 1, through the medium of the pinion B. and the-shaft C under the con i trol'of-the usual mechanism used to regulate the winding, which being ordinary and well known is not shown in the drawings.

'D is the belt shifting rod which carries the means used to move the driving belt intoand out of position to drive or sto iathe machine,

and is provided with an arm A portion only of the belt-shifting rod D is illustrated, thisbecause the rod and the means by which it controls the belt employed are 'of the ordinary, well-known construction.

-F is a weight'usually employed in roving frames. G is a cable connecting the said weight with the machine, and H is asheave over which said cable passes as shown. The said sheave H is carried by an arm a of a vertically swinging lover I, and this lever has two additional arms I) and c," the arm b being arranged to engage the arm E of the belt. shifting rod D, and the arm cserving for the pivotal connection of a depending latch J. This latch J has a toe d and when the said toe is in engagement with a stationary keeper K, it will be apparent that the weight F is prevented from rocking the lever I in the direction indicated by arrow N o. 2. When, however, the toed is moved-laterally out of engagement with the keeper K, and

the latch J is free to move upward, it willbe seen that the gravitation .of the weight F will forcibly swing the lever I in the direction indicated :by arrow No. 2, and through the medium-of said lever and the belt shifting rod sto the machine. The keeper K is preferab y formed in a stationary upright L.

M is a shaft which derives motion through well known mechanisn1 (not shown) from a suitable part of the machine. N'is a gear fixed on said shaft, and P is a vertically movable rack-bar intermeshed with the gear N and having a lateral arm R. Attached to the said arm R is an angle iron fixture S, and to the vertical arm of the said fixture is connected,'preferably in an adjustable manner, an upwardly-extending bar T which is preferably provided atits upper end with an an-- gularportion m and constitutes the tappet of my improvements. Attached to the rack A, preferably in an adjustable manner, is .a metallic bar U, and fixed to and extending laterally from said bar is a journal'V having a threaded socket r in its outer end. Loosely mounted on the said journal V an'dretained thereon by ascrew s and a washer t is a me.- tallichub W, and to the periphery of said hub is fixedly attached a tangentially -extending arm Y and a similarly extending,

comparativelylong arm Z. The rear end of the arm Z is preferably extended downward at the back of the hub W so as to form a counterbalance -W the office of which is to normally hold the arms. Y and Z in and return the same to the position shown in moved upward as before described, engages and then the gravitation of the weight F operates to rock the lever I and move the belt shifting rod D in the direction indicated by the arrow N 0.. 2, and in that way effects a stoppage ofthe machine.

It will be gathered from the foregoing that while simplel'and inexpensive in construction my improvements are reliable in operation and are well adapted to withstand the rough usage to. which vthe appurtenances of roving frames are-ordinarily subjected.

The construction herein shown and de scribed constitutes the-preferred embodiment of my invention, but it is obvious that in practice such changes, in the form, con struction and relative arrangement of parts may be made as fairly fall Within the scope of my invention as defined in the claims appended.

-Having described 'my invention, what I claim anddesire to secure by Letters-Patent,

1s: r v I 1. In a roving frame, the combination of a belt-shifting rod, a lever having an arm for engaging-and moving thebelt-shifting rod, a

weight, a cable connected to the weight and passed over a guide on the lever, a latch connected, to the said lever, a keeper for. engaging and holding the latch against movement in one direction, a belttraversing rack, means thereon for moving the latch out of engagement with the keeper; and a device movable at an angle to the belt-traversing rack and arranged to move the said means for moving thelatch.

2. In a roving frame, the combination ofa belt-shifting rod, a lever having an arm for engaging and moving the belt-shifting rod, a weight for swinging the said lever in one direction, a latch connected to the lever, a

keeper for engaging and holding the latch avaricei against movement in the said direction, a belt-traversing rack, swinging arms carried by tlie said rack; one of, saidarms being arranged to move the latch out of engagement with the keeper, and a device movable at an angle to the rack and arranged to engage the other arm.

3. In a roving frame, the combination of a belt-shifting rod, a lever having three arms,

one of which is arranged to engage and move the belt-shifting rod, a sheave on one of the other arms of the lever, apendent latch pivotally connected to the remaining arm of the lever, a weight for swinging the said lever in one direction, a cable connected to the weight and passed over the said sheave, a keeper for'engaging and holding thelatch against movement in the mentinn'cd direction, a belt-traversing rack, a bar connected tc said rack and having a lateral JOIlll'lLl, a

hub loosely mounted and retained on said journal and having arms one of which is arranged to engage the latch and also having a counterbalance, a tappet for engaging and moving the other arm of the hub, and means for moving the said tappet.

4. The combination in a roving frame, of means for shifting a belt, a latch, a connection between the latch and said means, a

weight connected with the said connection for moving the belt-shifting means when the latch is releasedfia keeper for engaging and holding the latch against movement in one' direction, a belt-traversing rack, means thereon for moving the latch out of engage ment with the keeper, and a device movable at anangle to the belt-traversing rack and arranged to move the said means for moving the latch. p I

In testimony whereof I have hereunto set my hand in presence of two. subscribing witnesses. MAURICE NOLET.
